change api version for rbac.authorization.k8s.io/v1beta -> v1, for all files in repo

[sirockin]

The resources with apiVersioin: rbac.authorization.k8s.io/v1beta in Chapter 3, and possibly elsewhere, need editing to remove the beta suffix from the version

Example:

$ kubectl apply -f 06-clusterrole.yml
error: unable to recognize "06-clusterrole.yml": no matches for kind "ClusterRole" in version "rbac.authorization.k8s.io/v1beta1"

Solution: Change api version in line 1:

apiVersion: rbac.authorization.k8s.io/v1
